MATERIAL HOLDER AND CARRIER FOR DYEING YARN 0N CHEESES.

Application filed July 26,

To all whom t may concer/n:

Be it known that I, WALTER BELL, a subject of the King of Great Britain,and a resident of the city of Hamilton, in the county of Wentworth,Province of Ontario, Dominion of Canada, have invented certain new anduseful Improvements in Material Holders and Carriers for Dyeing Yarn onCheeses, of which the following is the specication.

My invention relates to material holders and carriers for dyeing yarnson cheeses and the object of the invention is to devise an improved typeof holder and carrier for this purpose which will be more convenient andeconomical to use than those formerly7 used; a further object is tofacilitate they complete unwinding of the cheese so that there will beno tendency for the carrier to interfere with the free unravelling ofthe yarn oft1 the cheese during the unwinding operation. Other objectswill appear hereinafter.

y invention consists essentially of a holder and carrier comprising acoil spring, the ends of which are encased in perforated encasingelements, and a strip of covering material being wrapped about thespring and encasing elements, all as hereinafter more particularlydescribed and illustrated in the accompanying drawings in which Fig. lis a view of my improved holder and carrier, the lowermost of two endencasing elements used therewith being shown in section.

Fig. 2 shows a quantity of yarn wound upon my improved carrier andforming what is known in the art as a cheese, the yarn and a strip ofmaterial covering the carrier being shown in section.

Fig. 3 is a diagrammatic sideelevation of a form of kettle used fordyeing yarns, a ortion of the wall being broken away to s ow theinterior. For the sake of clearness, only a portion of the interiorcontents have been illustrated.

Fig. 4 is a sectional viewof a clamping ring used in connection with thekettle illustrated in Fig.`3.

This comprises the coil spring 2 the ends of which carry the encasementelements 3.

These elements 3 constitute sleeves which 1923. Serial No. 653,996.

posed about the sleeves and register with the interstices betweenadjacent coils of the spring.

7 is a strip of jute or other suitable textile material which is wrappedabout the s ring i2; and sleeves 3 and forms a covering t ,ere-

The spring 2, sleeves 3 and covering 7 constitute a holder and carrierupon which yarn may be wound.

The parts illustrated in Fig. 2 showing the yarn 8 wound upon the holderconstitute what is known in the art as a cheese, 9 being the free end ofthe yarn.

For convenience these cheeses will be hereinafter referred to by thenumeral 10.

11 is a cylindrical kettle having the false bottom 12 which divides thekettle into the upper chamber 13 and the lower chamber 14.

15 is a cover plate secured to the flanged top 16 of the kettle by bolts17.

This cover seals the upper end of the kettle.

18 are pipes the lower ends of which are secured to the false bottom 12and communicate with the lower chamber 14.

These pipes are provided throughout their length with perforations 19.

20 is a pipe communicating upwardly through the false bottom l2 and 21is a valve in said pipe.

22 is a pipe communicating with the bot# tom of the chamber 14 and 23 isa valve therein.

24 are clamping rings detachably mounted upon the upper ends of thepipes 18 and are provided interiorly with L-shaped slots 25 adapted toengage pins 26 near the upper ends of the pipes 18. The purpose of theseWill appear hereinafter.

The operation of my invention is as follows.

Before winding the yarn to be dyed upon the holder, the coveringmaterial 7 is wrapped thereabout. Any old scrap material such as jutesacking may be used for this purpose.

.The yarn 8 is then wound, in the usual manner, upon the holder, thematerial 7 constituting a foundation for the innermost windings of theyarn.

When this operation is completed the parts are as illustrated in Fig. 2and constitute a cheese. i

These cheeses are then inserted within the kettle, being piled one uponthe other so that the pipes 18 pass upwardly therethrough.

The clamping rings 24 are then mounted upon the upper ends of the pipes18, these rings being pressed downwardly so that the springs 2 and thecheeses -as a whole are compressed and forced tightly together.

As the clamping ring is pressed downwardly the pin 26 passes upwardly inthe slot 25 and by giving the ring a slight turn the pin 26 passes intothe off-set end portion of the L-shaped slot 25 and secures the ringagainst longitudinal motion.

In this position the cheeses are tightly compressed together.

While only a few of the pipes 18 and of the cheeses have been includedin Fig. 3 it is to be understood of course that the kettle will containas many of these as possible.

The construction and operation of the kettle itself is of standard typeand forms no part of my present invention and therefore detaileddescription is not thought necessary. y

'Ihe operation of dyeing yarn in such a lliettle however may be briefiystated as folows.

When the cheeses have been properly mounted in position upon the pipes18 the cover 1 5 is secured in place. The dyeing solution is then pumpedin, say through the pipe 22, and enters the bottom chamber 14 from whichit passes upwardly into the pipes 18 and out through the perforations i19 in these pipes.

It is then forced outwardly through the cheeses and enters the upperchamber 13 from which it passes downwardly through the false bottom 12into the pipe 20. The

Y therethrough.

direction of flow in this operation is indicated by the arrows in Fig.3.

When this flow has continued for a suficient length of time it may bereversed in direction and made to flow inwardly through the pipe 20 andoutwardly through the pipe 22. In this case instead of flowing outwardlythrough the cheeses it flows inwardly therethrough from the chamber 13into the pipes 18.

I am aware that coil springs have been used for this purpose but theiruse has not proved satisfactory for various reasons, one of which hasbeen the diiiiculty of unwinding the cheese, it having been found thatthe end of the spring interferes with the free unravelling of the yarn.

Formerly these springs have been covered by a knitted stockinette. Thishad the disadvantage that it was expensive and difficult to put on andtake off the spring, the operation requiring considerable time andusually the stockinette was damaged in the operation. Y

Further the ends of the stockinette interfered with the free unravellingof the yarn.

It is to be noted that the perforations 6 in the sleeves register withthe interstices between adjacent coils of the spring and thus permitfree passage of the dyeing liquid From the foregoing it will be observedthat I have devised valuable improvements in holders and carriers forthe purpose specified which will prove of great value.

`What I claim as my invention is:

A material holder and carrier of the class u,described comprising `acoil spring, and a sleeve encasing each end thereof, each sleeveprovided with a series of helically disposed perforations registeringwith the interstices between adj acent coils of the spring.
